Exodus 13:13 Meaning and Commentary

Exodus 13:13

And every firstling of an ass thou shalt redeem with a lamb,
&c.] Which was given to the priest for it; and according to the Jewish canon F6, it might be redeemed with that only;

``not with a calf, nor with an animal (a goat or a ram, as Bartenora interprets it), nor with a lamb slain, or torn to pieces.''
Jarchi thinks the ass only was to be redeemed, and not the firstling of any other unclean creature, but his reasons are insufficient; all unclean creatures, as horses, camels, dogs, swine are included in it, as should seem from ( Numbers 18:15 ) and this is the rather particularly mentioned, because there was a greater plenty of them than of horses and camels, and because they were very useful creatures; and if these were to be redeemed, then much more those of less value, and less useful. Hence might arise the story and calumny, as some have thought, of the Jews worshipping an ass's head: and if thou wilt not redeem it, then thou shall break its neck;
cut off its head on the back of the neck with a knife or cleaver, such as butchers use, as the Misnah F7, and its commentators, interpret it, so that the owner should have no profit by it: and all the firstborn of man amongst thy children shall thou redeem;
with the price of five shekels of the sanctuary, and within thirty days of the birth of it, ( Numbers 18:16 ) and these being to be redeemed as the unclean beasts were, shows that men are by nature unclean, and even the firstborn, whose names are written in heaven, the elect of God, and need redemption by the blood of the Lamb.

Exodus 13:13 In-Context

11 "And when the Lord takes you into the land of the Canaanites, the land he promised to give you and your ancestors,
12 you must give him every firstborn male. Also every firstborn male animal must be given to the Lord.
13 Buy back every firstborn donkey by offering a lamb. But if you don't want to buy the donkey back, then break its neck. You must buy back from the Lord every firstborn of your sons.
14 "From now on when your son asks you, 'What does this mean?' you will answer, 'With his great power, the Lord brought us out from Egypt, the land where we were slaves.
15 The king of Egypt was stubborn and refused to let us leave. But the Lord killed every firstborn male in Egypt, both human and animal. That is why I sacrifice every firstborn male animal to the Lord, and that is why I buy back each of my firstborn sons from the Lord.'
